RELATED APPLICATIONS

This application is a divisional of and claims priority to U.S. patent application Ser. No. 15/476,975 filed Apr. 1, 2017, and titled “REDUCE PULL LEASH APPARATUS AND METHODS” (Attorney Docket No. LAD-001-US), which is hereby incorporated by reference herein in its entirety for all purposes.

FIELD

The present application relates to leashes for walking animals and more specifically to reduced pull leash apparatus and methods.

BACKGROUND

Dogs are wonderful companions and walking them can be a pleasant experience. For example, dogs provide a reason to get outside into nature, and are ideal walking or running partners.

A dog is typically walked on a leash that is connected to a collar placed around the dog's neck. Ideally, the leash is used to gently guide or direct the dog in a direction of travel. However, when a dog is untrained or gets excited, such as when the dog sees a squirrel or another dog, the dog may pull on the leash. This may result in the dog pulling, or even dragging, the person holding the dog's leash. This may be dangerous to both the dog and the person walking the dog. For example, the dog may be chocked by the collar and even may be injured. Likewise, the person walking the dog may be pulled off balance or knocked down. In some cases, the dog walker may suffer joint injuries from an unexpected pull and/or from multiple pulling events that occur over time. Example pull injuries include wrist, elbow and shoulder strains.

Methods and apparatus for reducing injuries to dogs and people who walk dogs are desired.

DETAILED DESCRIPTION

In accordance with one or more embodiments provided herein, a leash device is provided that reduces the burden of walking a dog or other animal that pulls. In some embodiments, a reduced-pull leash device includes a first leash section that is extendible and that couples to a top portion of a dog harness, such as near a back region of a dog. The reduced-pull leash device also includes a second leash section that couples to a front portion of a dog harness, such as near a neck region of the dog. The first and second leash sections also couple to and/or form part of a dog leash.

When a dog is using the reduced-pull leash device, the first leash section extends when the dog begins to pull on the dog leash. At this stage, the dog feels pulling along its back due to the first leash section. The first leash section extends until the second leash section becomes taut. Once the second leash section becomes taut, a lateral force is generated at the front location of the dog because of the pull on the second leash section. The lateral force at the front of the dog causes the dog to be pulled sideways and/or rotate. The harder the dog pulls, the more the dog rotates. This makes it much harder for the dog to pull the person holding the dog leash. The lateral and/or rotational force has been found to discourage the dog from pulling, and to train the dog to stop pulling once it feels the first leash section stop extending. Numerous other embodiments are provided. These and other embodiments are described further below with reference to FIGS. 1A-4.

FIG. 1A is a schematic representation of a reduced-pull leash device 101 provided in accordance with the present invention. The reduced-pull leash device 101 includes a first leash section 103 a that is extendible and that couples to a top portion of a dog harness 105, such as near a back region of a dog 107. The reduced-pull leash device 101 also includes a second leash section 103 b, that in some embodiments is of a fixed length (e.g., is not extendible), and that couples to a front portion of the dog harness 105, such as near a neck region of the dog 107. The first and second leash sections 103 a, 103 b also couple to a dog leash 109. The dog harness 105 may be any conventional dog harness. The dog leash 109 may be any conventional dog leash such as a fixed length or retractable dog leash.

The first leash section 103 a may be formed of any extendible, stretchable and/or expandable material such as a natural or synthetic rubber, neoprene, or the like. In some embodiments, the first leash section 103 a may include one or more bungee cords. The second leash section 103 b may be formed from leather, nylon, chain, cable or any other suitable material that is sufficient in strength to not break when pulled on by a dog or other animal to be walked.

In some embodiments, a first end of the first leash section 103 a and a first end of the second leash section 103 b may couple to a ring, carabiner, hook or similar device 111, which may also couple to the leash 109. A second end of the first leash section 103 a may couple to the dog harness 105 at a back region of the dog 107, such as with a ring, carabiner, hook or similar device 113. A second end of the second leash section 103 b may couple to the dog harness 105 at a neck region of the dog 107, such as with a ring, carabiner, hook or similar device 115. Other coupling devices and/or locations may be used.

The length of the first leash section 103 a and the length of the second leash section 103 b are configured so that the first leash section 103 a extends and/or expands when a dog pulls on the dog leash 109 until the second leash section 103 b becomes taut. Once the second leash section 103 b becomes taut, a lateral force is generated at the front location (neck region) of the dog 107 so as to pull the dog laterally. For example, as shown in FIG. 1B, as the dog 107 pulls forward with a force F1, the person (not shown) walking the dog 107, exerts an opposite force F2 to stop the dog 107 from moving forward. In response to these oppositely directed forces F1 and F2, the first leash second 103 a is stretched and extends as indicated by double arrow 117.

First leash section 103 a expands until second leash section 103 b becomes taut. At this point, any additional force from the person walking the dog 107 creates a lateral and/or rotational force F3 that causes the dog 107 to be pulled laterally as the dog 107 tries to pull forward. The harder the dog 107 pulls, the more the dog 107 rotates. This makes it much harder for the dog 107 to pull the person walking the dog 107. The lateral and/or rotational force has also been found to discourage the dog 107 from pulling, and to train the dog 107 to stop pulling once it feels the first leash section 103 a stop extending.

FIGS. 1C and 1D are top schematic illustrations of the forces generated on the dog 107 as it pulls. As shown in FIG. 1C, when the dog 107 initially pulls on the leash 109, section 103 a begins to extend and the force exerted by the dog 107 pulling forwarded is directed through first leash section 103 a primarily in-line with the dog 107 (e.g., along the y-axis in FIG. 1C). Once the dogs 107 pulls hard enough that the first leash section 103 a extends to a point at which the second leash second 103 b becomes taut, the second leash section 103 b pulls the dog 107 in both a backward (y-axis) and lateral (x-axis) direction as shown by arrow (force) F3.

The force F3 pulls the dog 107 laterally and causes the dog 107 to pivot because the back legs of the dog 107 become fixed pivot positions about which the dog 107 can rotate due to the lateral (x-axis) force component of force F3. The harder the dog 107 pulls, the more the dog 107 is pulled sideways or rotates. As mentioned, this makes it much harder for the dog 107 to pull the person walking the dog 107. It has also been found to discourage the dog 107 from pulling and to train the dog 107 to stop pulling once it feels the first leash section 103 a stop extending.

FIG. 1E is an alternative embodiment of the reduced-pull leash device 101 in which the second leash section 103 b is coupled to the harness 105 and/or the first leash section 103 a with an additional leash section 103 c. The additional leash section 103 c may be of a fixed length or extendible and is used to prevent the dog 107 from becoming tangled in the second leash section 103 b when the second leash section 103 b is loose (not taut). The additional leash section 103 c may be made from the same material as the first leash section 103 a, the second leash section 103 b, or from any other suitable material. The additional leash section 103 c may be coupled to the harness 105, the first section 103 a, the coupling device 113 or another other suitable location.

FIG. 1F is an alternative embodiment of the reduced-pull leash device 101 in which the second leash section 103 b is coupled to the neck region of the harness 105 with an additional mounting piece 119. The additional mounting piece 119 is designed to increase the rotational torque exerted on the dog 107 by the second leash section 103 b during pulling by the dog 107. In particular, the additional mounting piece 119 moves the connection point of the second leash section 103 b laterally from the harness 105 in the neck region of the dog 107. In some embodiments, the additional mounting piece 119 may include an alarm (not separately shown in FIG. 1F) that generates a sound when the second leash section 103 b is taut and pulls on the additional mounting piece 119 with greater than a predetermined force. Additionally or alternatively, the additional mounting piece 119 may vibrate and/or shock the dog 107 when the second leash section 103 b becomes taut and pulls on the additional mounting piece 119 with greater than a predetermined force. For example, FIG. 1G illustrates a simplified electrical circuit 121 for providing one or more of an alarm, a vibration and/or a shock in response to the second leash section 103 b becoming taut. With reference to FIG. 1G, the second leash section 103 b may be coupled to a spring activated switch 123 (e.g., via a coupling 125) that closes electrical circuit 121 when the switch 123 is pulled with a predetermined force or greater by the second leash section 103 b. Closing the electrical circuit 121 causes a battery 127 to deliver electrical energy to one or more of an alarm 129, a vibration mechanism 131 and/or an electrical shock mechanism 133 to provide one more of an auditory warning, a vibration or a shock to dog 107 to warn dog 107 to stop pulling. This switch 123 may release (e.g., under spring action) and open the electrical circuit 121 when the dog 107 stops pulling so as to stop the alarm, vibration and/or shock. The alarm, vibration and/or shock may therefore be “pull-activated.” In at least one embodiment, one or both ends of the additional mounting piece 119 may be coupled to the dog harness 105 to improve stability, such as via one or more straps (not shown) extending between the ends of the additional mounting piece 119 and dog harness 105 (e.g., near the coupling device 113 (FIG. 1E) or another suitable location).

In some embodiments, the lengths of the first and second leash sections 103 a, 103 b are selected so that the first leash section 103 a extends when a dog pulls on the dog leash 109 until the second leash section 103 b becomes taut as shown in FIG. 1B, for example. The length of the first leash section 103 a may depend on many factors such as the size of the dog 107, how long a user wants the reduced-pull leash device 101 to be as the length of first leash section 103 a effectively increases the length of the leash 109, the position of the coupling fastener 113 relative to the coupling fastener 115, how much the first leash section 103 a extends, etc. Similarly, the length of the second leash section 103 b may depend on many factors such as the size of the dog 107, how much force a user wants to exert before the second leash section 103 b becomes taut, the position of the coupling fastener 113 relative to the coupling fastener 115, how much the first leash section 103 a extends, etc. In some embodiments, the first leash section 103 a may be about ½ to about ¾ of the length of the second leash section 103 b. In one particular embodiment, the first leash section 103 a may be about 5-15 inches, and in some embodiments about 8-12 inches, and the second leash section 103 b may be about 15-30 inches, and in some embodiments about 18-25 inches. Other first and/or second leash section lengths may be used.

In some embodiments, the length of the first leash section 103 a and/or the length of the second leash section 103 b may be adjustable, such as by using an adjustable length strap slider or similar mechanism.

FIG. 2 is a schematic illustration of another alternative reduced-pull leash device 201 provided in accordance with embodiments herein. With reference to FIG. 2, the reduced-pull leash device 201 includes a first leash section 103 a having a first quick release 203 a and a second quick release 203 b. For example, the first and second quick releases 203 a, 203 b may be carabiners, quick release helmet fasteners or the like. Use of quick releases 203 a, 203 b allows different length and/or elasticity first leash sections 103 a to be easily used. The second leash section 103 b similarly may include a quick release 205 for coupling to the harness 105 (and/or to the leash 109).

FIG. 3A is a schematic illustration of another alternative reduced-pull leash device 301 provided in accordance with embodiments herein. With reference to FIG. 3A, in the reduced-pull leash device 301, the second leash portion 103 b is formed from the leash 109. For example, a mounting ring 303 or other coupling may be attached to the leash 109 via a strap 305 or other material to define a desired length for the second leash section 103 b. The first leash section 103 a may couple to the mounting ring 303 as shown, for example.

In some embodiments, the second leash section 103 b and/or the leash 109 may be provided with mounting locations 307 (FIG. 3B) that allow the mounting ring 303 to be coupled at any desired location along leash 109. This allows for easy adjustment of the length of the second leash section 103 b relative to the first leash section 103 b. Any suitable mounting mechanism may be used to couple the strap 305 to the leash 109 (e.g., snaps, plugs, etc.). In other embodiments, the first leash section 103 a may couple directly to any of the mounting locations 307 (e.g., without the mounting ring 303) to set a desired length of the first leash section 103 a relative to the second leash section 103 b.

As stated, the mounting locations 307 may be formed in the leash 109, the second leash section 103 b or both. In some embodiments, the second leash section 103 b is created by attaching the first leash section 103 a to one of the mounting locations 307 of the leash 109 (so as to define the second leash section 103 b and its length).

FIG. 4 is a schematic illustration of another alternative first leash section 103 a. With reference to FIG. 4, the first leash section 103 a is coupled to a first quick release 403 a and a second quick release 403 b. For example, the first and second quick releases 403 a, 403 b may be carabiners, quick release helmet fasteners or the like. Use of quick releases 403 a, 403 b allows different length and/or elasticity first leash sections to be easily used. In the embodiment shown, the first leash section 103 a includes looped ends 405 a, 405 b that allow the first leash section 103 a to be quickly attached to or removed from the quick releases 403 a, 403 b. Additional first leash sections of different thicknesses and/or elasticities may be used for or added to the first leash section 103 a. For example, FIG. 4 illustrates first leash sections 103 a′ and 103 a″ which have different thicknesses and which may be used in place of or in addition to the first leash section 103 a. In this manner, the length of the first leash section 103 a may be changed, or the amount of force required to stretch the first leash section 103 a may be increased or decreased as desired.

The foregoing description discloses only example embodiments of the invention. Modifications of the above disclosed apparatus and methods which fall within the scope of the invention will be readily apparent to those of ordinary skill in the art. For example, the second leash section 103 b may be of a fixed length or, in some embodiments, extendible but requiring more force than the first leash section 103 a to extend. In such cases, the second leash section 103 b may be formed from natural or synthetic rubber, neoprene, or the like, for example. In one particular example, the first and second leash sections 103 a, 103 b may be formed from the same material but the second leash section 103 b may be thicker than the first leash section 103 a so as to require more force to extend. While described primarily with regard to dogs, it will be understood that the reduced-pull leash device described herein may be employed with other animals.
